ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 426,316, dated April 22, 1890. Application filed January 18, 1890. Serial No. 337,327. (No model.)

To all whom it may concern.-

Beitknown thatI, CARL A. PETTERSEN, acitizen of the United States of America, residing at Lake Crystal, in the county of Blue Earth and State of Minnesota, have invented certain new and useful Improvements in Attachments for Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention has reference to magazine attachments for stoves; and it consists in the improvements hereinafter described and set forth,'whereby a complete magazine attachment is provided that may be readily used in connection with top-feed stoves, and enable a proper quantity of fuel to be always kept in readiness for use and conveniently supplied to the fire whenever and in such quantity as may be desired.

The improvement is especially designed for soft-coal stoves, where it is a great consideration to feed the fuel without the necessity for opening the doors to discharge gas and other objectionable products to the room.

'In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved attachment, showing the valve-section opened for the purpose of full feed; and Fig. 2 is a vertical sectional elevation of the said attachment, its valvesection being closed, and its position within it stove being generally represented by dotted mes.

The body portion'of my improved attachment consists of a vertical cylinder A, the upper edge portion of which is slightly flared to present an annular shoulder a to support or suspend the attachment within the body of the stove from the opening in the top plate thereof. A cover b is of such diameter that it is adapted to close the upper end of the cylinder below the top edge thereof, and the said cover is preferably provided with an opening for effecting its removal and adjustment by means of the ordinary lid-poker. The lower part of said cylinder is shaped, as shown, so that an extension 0 depends below the balance, the lower edge of said extension terminating in an inwardly and downwardly curved lip d, the edge of which is rounded off, as shown.

The valve-section B is of the shape shown most clearly in Fig. 1, and consists of a semicircular body portion e, of somewhat larger diameter than the cylinder A, said section being pivotally connected to the cylinder A by means of upwardly extending ears f, through which pivots g, seated in the cylinder, pass. The body portion 6 of the valvesection is of such size that it closes or covers the opening formed in the side of the cylinder by the extension 0 on the opposite side,

and said section B has a cut-off h, consisting of a curved portion depending from the portion 6 and of such size that it will close all of the opening at the lower end of the cylinder save what is guarded by the stationary lip. The cut-off carries on its outer side a loop '6, with which connects the inner end of a horizontal bar 0, the under edge of which is provided with ratchet-shoulders j, adapted to bear, when adjusted, against the inner side of the stove-body, adjacent to a vertical slot formed therein and through which said bar 0 plays. The outer end of this bar carries a handle is, preferably protected by a guardplate Z, and the major portion of said bar is provided with a series of transverse holes on, so that the bar is adjusted to regulate the position of the cut-off plate, and hence the quantity of fuel fed. The ratchet-shoulder will bear against the inside of the stove-body adjacent to the lower end of the slot in the same, and thereby preventing the cut-off section from being moved under the pressure exerted by the coal, while inward movement is prevented by passing a pin through the opening 7 m next adjacent to the stove-body.

From the foregoing description it will be apparent that the improved magazine attachment is complete in itself, and that it can be applied to existing stoves of all the top-feed type, and that the cut-01f may be readily operated, so that the fuel can be fed in any desired quantity Without opening any of the doors or parts that would result in the admission of gas or other products into the room. By closing the cut-01f the lid of the attachment may be removed and the same conven iently filled. Inasmuch as the cut-off tightly closes the bottom of the cylinder, no bad effects will be experienced from the fire during the filling operation. moved to allow the feed of the fuel, the stationary lip directs it evenly and regularly onto the fire, and at the same time prevents too rapid a descent, that would be the case if such stationary lip were omitted.

I am aware of the prior construction wherein a magazine-pot was removably suspended in the upper portion of a stove, the bottom of said pot being closed by a 'two-part slide, each section of which was pivoted in the side of the pot and both geared together, so that one could be operated to cause both to recede from each other to open the magazine. My improvementwill be principally distinguished from such construction in that I provide the lower end of the cylinder with a permanent lip and having a movable cut-off to coact with said lip,'other features of difference existing which are specifically referred to in the claims. An important result secured by my improvement in connection with stoves having their feed-openings at one side of the vertical center is that the attachment can be so adjusted that it will be out of the way of the direct action of the combustion, and the fixed lip will lVhen the cut-off is 1 lower end of the cylinder, a movable cut-off' section for cooperating therewith to close 7 said lower end, and means for operating said cut-off, substantially as set forth.

2. The combination, in a magazine attachment for stoves, of a vertical cylinder having a shouldered upper end, a cap for closing the same, a semicircular extension at the lower end, terminating in an inwardly-inclined lip, an independent semicircular section of larger diameter than the cylinder, pivoted thereon in the same plane with the extension thereof and having a curved cut-off plate, together with operating means therefor, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

CARL A. PETTERSEN.
